 OVALLE, Chile, Feb 10 (Reuters) - A long drought has dried
up hydroelectric power production in Chile, sending electricity
costs soaring and making renewable power sources like wind,
solar and geothermal more attractive, particularly to
energy-hungry miners reaping a copper windfall.
 "Renewable energies require a greater investment but they
have low production costs," said Mabel Weber, an energy analyst
with Banchile Investments. "The more prices rise, the more
viable alternative energies look."
 Scarce rains from the La Nina weather pattern have slashed
hydroelectric output in Chile, the world's top copper producer.
Generators must rely on plants powered by costly imported oil
and gas, compounding inflation risks in the booming economy.
 Energy prices have nearly tripled in five years, leading
companies to covet the cost stability offered by wind, solar
and geothermal power.
 Chile's mining sector in particular, which consumes a third
of the country's power, has the means and motive to stabilize
its energy costs by investing in new technology now that copper
prices are at record highs.
 State miner Codelco has committed $700 million to a 250 MW
wind farm that may be the largest in Latin America when
finished, and world No. 3 copper mine Collahuasi is exploring
geothermal energy to tap Chile's immense volcanic activity.

 "With copper at $4 per pound, you can pay what you want,"
said Francisco Aguirre, executive director of Santiago
engineering firm Electroconsultores.
 "So miners have the luxury of paying more for energy,
including the development of renewable sources."
 If Chile recovers quickly from its energy crunch, though,
experimental energy may soon be priced out of the market.
 Visiting the expansion of Chile's second-largest wind farm,
the 48 MW Monte Redondo complex 200 miles (325 km) north of
Santiago, Energy and Mining Minister Laurence Golborne said on
Tuesday that an end to Chile's drought could end the current
spike in power prices.
 Golborne suggested electricity costs could soon subside
from $150 per MWh to roughly $90 per MWh in the long term, but
he said wind power remains a promising resource given Chile's
extensive wind-swept coastline.
 "The investment costs are high for renewable energy,"
Golborne said. "But this installation shows that it is possible
to turn this energy alternative into a competitive option."
 ENERGY SQUEEZE
 President Sebastian Pinera said on Wednesday the government
had readied measures to avoid energy rationing if drought
conditions continue, sapping the hydro power that generated
most of the electricity in the country's central grid until
last year. [ID:nN09226155]
 Analysts in Chile play down the risk of energy shortages,
but warn of higher prices and the possibility of blackouts
given reliance on backup generators and imported oil and gas.
Chile was hit by several blackouts last year after a massive
earthquake damaged transmission infrastructure.[ID:nN03272253]
 Chile's central grid supplies more than 90 percent of the
population and is most likely to be hit by the energy squeeze
because of its reliance on hydro power. The far northern grid,
which powers miners in the copper-rich Atacama desert, relies
on thermoelectric plants fired by coal, gas and diesel.
 But key copper mines in central Chile, like the 400,000
tonnes per-year El Teniente mine owned by state giant Codelco,
and Anglo American's (AAL.L: Quote) Los Bronces, rely on the country's
main grid and were briefly hit by blackouts last year, at times
slowing output.
 The extended drought has also hurt the bottom line of major
energy players like regional power group Enersis (ENE.SN: Quote)
(ENI.N: Quote) and its local generator Endesa Chile (END.SN: Quote) (EOC.N: Quote),
which reported last month that their bottom lines suffered in
2010 due to reliance on fuel-driven plants.
 The sector is currently supported by Chile's requirement
that generators incorporate non-conventional renewable energies
in their output, beginning with 5 percent last year and rising
to 10 percent in 2024.
 Chile's previous energy minister discussed strengthening
the law to require 20 percent alternative energy by 2020, but
the government appears to have backed off that goal amid the
spike in energy prices.
 "Today there is no country in the world with 20 percent of
its power produced by renewable energy. However that is the
long-term aspiration of our country," Golborne said on Tuesday.
"Most countries that approach that ratio also count on coal,
fossil fuels and nuclear energy."
 Chile's alternative energy law counts output from
hydroelectric plants smaller than 40 MW along with sources like
wind power, which has grown to around 170 MW capacity in Chile
since the first turbines were installed in 2008.
 Environmental concerns have snagged mega-projects like the
2,750 MW Patagonian dam project HidroAysen and the 2,350 MW
coal-fired Castilla plant proposed by Brazil's MPX Energia.

plant in August after Pinera urged its relocation amid public
outcry over fears the project would harm an endangered penguin
reserve. [ID:nN26201975]
 Last year's devastating earthquake also pushed back
completion dates for two new 340 MW coal plants.
